Intrauterine hydrosalpinx

Area of Science:

• Gynecologic pathology
• Reproductive medicine
• Surgical oncology

Background:

• Intrauterine hydrosalpinx is a rare condition involving fallopian tube dilation within the uterine myometrium.
• Distinguishing such masses from neoplastic lesions is crucial for accurate diagnosis and management.

Observation:

• A case presented with a large intramyometrial cyst, initially suspected to be a degenerated leiomyoma.
• Histopathological examination revealed a true cyst lined by fallopian tube epithelium.

Findings:

• The lesion was a significantly dilated fallopian tube within the uterine wall, forming a large cyst.
• The cyst was lined by characteristic tubal epithelium, confirming its origin.
• The term "endosalpingoma" is proposed for this entity due to its neoplastic-like presentation.

Implications:

• This case highlights the importance of considering rare gynecologic entities in the differential diagnosis of uterine masses.
• Accurate histopathological evaluation is essential to differentiate endosalpingoma from uterine neoplasms.
• The proposed term aids in classifying and communicating this unusual finding in gynecologic pathology.
